Rural Settlement Dynamics in a Rapidly Urbanizing Landscape: Insights from Satellite Remote Sensing and Archaeological Field Surveys in Zanzibar, Tanzania

ABSTRACT In Africa, rapid urbanization covers archaeological sites and limits the utility of traditional archaeological field survey methods. This is not only a crisis for archaeological heritage conservation, but it also distinctly impacts anthropological understandings of African urban trajectories since much evidence for precolonial urbanism lies within areas of rapid expansion. However, high-resolution multitemporal satellite data may facilitate reconstructions of urban growth in African cities, enabling archaeological surveys to target undeveloped areas for prospection within the interstices of modern urban development. This paper describes an application of satellite remote sensing for archaeological prospection within the rapidly urbanizing hinterland of Zanzibar Stone Town, a UNESCO World Heritage site. Survey results reveal settlement trajectories around the city over the last millennium, drawing attention to the role of rural agricultural land as a factor in the emergence of precolonial urbanism and the continued significance of rural places as urbanization progressed into the Colonial era.

Depopulation and Changes in Habitat Type in Rural Areas in Aragón (Spain)

Objective: The study aims to examine recent transformations in rural habitats undergoing depopulation in Aragón, Spain, between 2010 and 2018. It seeks to verify changes in habitat concentration patterns and identify the underlying factors. Theoretical Framework: Drawing upon theories of rural exodus and demographic shifts, the research employs the Colas Index (Colas, 1945) to analyze habitat types—dispersed or concentrated. It recognizes the influence of agricultural changes, service provision challenges, and territorial dynamics on rural settlement patterns (Escolano and de la Riva, 2003; Nuninger et al., 2021). Method: The investigation focuses on depopulated municipalities in Aragón, utilizing a comparative analysis of the Colas Index from 2010 to 2018. Administrative boundaries define the study's territorial units, enabling the quantification of habitat changes and an assessment of their direction. The analysis integrates demographic and settlement dynamics to understand habitat evolution. Results and Discussion: Findings indicate varied habitat transformation processes across municipalities, confirming the heterogeneity of the rural landscape (Pinilla and Sáez, 2017). While transformations are not universal, they challenge the traditional link between depopulation and habitat concentration. The Colas Index proves valuable for characterizing habitat dispersion levels, yet its limitations in concentrated areas are acknowledged. Methodological constraints related to administrative boundaries and the complexity of rural-urban continua are also discussed. Research Implications: This study contributes to a nuanced understanding of depopulation impacts on rural habitats, informing territorial planning and demographic policies. It underscores the need for tailored strategies that consider local habitat variability and the potential for revitalization efforts in select areas. Originality/Value: By highlighting the diversity of habitat transitions amidst depopulation, the research offers fresh insights into rural settlement dynamics. Its value lies in demonstrating that depopulation no longer universally leads to habitat concentration, thus updating the scholarly discourse on rural transformation in Spain.

Long-Term Settlement Dynamics in Ancient Macedonia: A New Multi-Disciplinary Survey from Grevena (NW Greece)

This paper discusses the evolution of human settlement in ancient Macedonia from the Neolithic to the Late Roman periods, based on the results of a new multi-disciplinary and multi-scale archaeological survey in northern Grevena (NW Greece). Building upon an unpublished (legacy) survey, we developed a GIS-structured workflow that integrates site-revisiting and surveying strategies (material collection and test pits) with multi-temporal remote-sensing analyses, offering analytical information about site distribution, characterisation, dating, and taphonomy. Notably, the new study led to a 64% increase in the number of known sites. The combined results indicate that prehistory is less represented in the surface record than historical periods, likely due to the impact of soil erosion episodes. The Late Bronze Age and Early Iron Age saw increased site numbers and the emergence of a settlement structure that characterised the area until the Hellenistic period. During the Roman period, the pattern shifted from a seemingly limited use of the landscape towards a model of more extensive habitation. This was driven by the appearance of new rural sites that introduced a land-use regime designed to support agricultural intensification by implementing anti-erosion measures, such as field terraces.

Fossil spring records from central Sudan reveal paleoenvironmental and settlement dynamics in the Eastern Sahel during the last 30 ka

Knowledge of past environmental change and prehistoric settlement dynamics in the Sahel east of the Nile is limited due to the scarcity of suitable sedimentary archives and archaeological sites. Here we present tufa-based paleoenvironmental records from the area of NW Butana (central Sudan, ∼55 km southeast of the Nile River) which show that increased rainfall and spring activity occurred in several discrete intervals during the last ∼30,000 years. Lithostratigraphic data combined with phytolith, malacological, paleopedological, and stable carbon isotope records revealed humidity peaks during late MIS3 and the early and middle Holocene. Gaps in lithological records correlated with dry periods of the Last Glacial Maximum and Younger Dryas. Minor wet pulses coinciding with Late Glacial interstadials indicate an early intensification of the African monsoon, which implies that a sharp climatic boundary existed between the Sahel and the Sahara during this period.These new paleoenvironmental records, together with archaeological evidence from Butana, provide a unique opportunity for understanding human ecology in the eastern Sahel. The peoples who inhabited this dryland area 30+ km from the Nile Valley could not rely on its relatively predictable resources of riverine, floodplain and lake habitats. New models of subsistence and settlement, and strategies of adaptations to seasonal and interannual environmental variability are needed.

Analysis of Dispute Settlement Dynamics Analysis of behaviors in the import tariffdispute between the United States and China

The ongoing dispute over import tariffs between the United States and China has emergedas a significant concern within the global economy since 2018. Chinese retaliation, triggeredby the United States’ imposition of import taxes on Chinese imports as a response to unfairtrade practices including intellectual property theft and detrimental subsidies, furtherintensified global trade tensions. Both nations ultimately sought resolution of the importtariff dispute by appealing to the World Trade Organisation (W.T.O.). This study employs adescriptive qualitative approach, combining International Relations theory and caseanalysis to interpret the diplomatic strategy and conduct in settling this trade conflict.Analysis was conducted on data obtained from papers, official websites, and books toinvestigate the resolution of disputes through the World Trade Organisation (WTO) and theeconomic consequences of trade retaliation. The findings underscore the intricacy ofinternational economic relations, and the conduct exhibited by participants in managingconflicts. This study highlights the crucial significance of international organizations inpreserving trade stability and offers valuable understanding of the mechanisms involved inresolving disputes related to intricate import tariff conflicts.

Climate-conscious archaeology: contextualizing drought and history in the Chesapeake

This paper adopts a climate-conscious approach to archaeology, integrating environmental scientists’ definitions of extended droughts and megadroughts into the analysis of historical processes in the Chesapeake region of North America. We explore the relationship between drought conditions and historical processes through three case studies: Ancestral Monacans’ migration, the settlement dynamics in the Middle Potomac, and the emergence of the Powhatan chiefdom. Employing the Palmer Modified Drought Index as a paleoclimatic proxy, the research assesses how variations in rainfall and drought influenced migration, agriculture, and political formations. The findings underscore the complex interplay between Native history and environmental conditions, suggesting that the impact of climate on historical processes ranged from negligible to substantial, particularly with the adoption of maize-based agriculture. This study highlights the benefits of a climate-informed archaeological inquiry that recognizes the historically contingent ways in which climatic variability has shaped and is entangled with social change.

Long-Term Hierarchic Changes in Settlement Systems at Geographic ‘Edges’

ABSTRACT Sparsely populated geographic edges of colonised nations exhibit heterogenous historical demographic trajectories. In this study, we analyse the longitudinal evolution of the settlement system in Northern Australia to quantify and visualise relative settlement dynamics over 165 years. We extend the existing literature by deviating from analysing each township as an individual entity, instead focusing the analysis on relativities within the entire settlement system. We quantify settlement and systemic volatility through measurement and visualisation of relative settlement sizes using rank-sizes and document rank-size changes between 1856 and 2021. We analyse rapid and non-synergic shifts in rank-trajectories and demonstrate rank-trajectories for selected settlements by types. We found that the expansion of a fly-in-fly-out workforce in the resource sector since the 1980s has meant less turbulent trajectories for the settlement system in the North could potentially open prospects for more sustainable population growth policies while relocating the risks of resource dependency in employment and growing unemployment during economic bust from edges to core areas. Beyond annotating the evolution of the settlement system in Northern Australia, this study demonstrates the potential for policy, economic conditions and definitional peculiarities to affect volatility in the settlement system at geographic edges elsewhere.

“Gravettians in the Altmühl Valley”? Comprehensive Reassessment and New Data from the Sequence from the Abri I im Dorf (Neuessing, Bavaria, Germany)

Due to the high density of cave and rock shelter sites, the Altmühl Valley is one of the most essential regions of southern German Palaeolithic research. The site presented in this paper, the Abri I im Dorf, lies within the main concentration of Palaeolithic sites found in this valley, extending along its lowest stretch between Riedenburg and its confluence into the Danube in Kelheim. We present the results achieved in reassessing the archaeo-stratigraphic sequence uncovered during the excavation campaign of 1959, including the first radiocarbon dating and comprehensive analysis of the lithic, faunal and bone industry evidence. Radiocarbon evidence points to occupations dated to ca. 27 ka cal BP. At the same time, the features of the lithic assemblage (blade industry with a predominance of burins and an important presence of backed tools) fit those of Late/Final Gravettian technocomplexes in the Danube region. However, the characteristic evidence traditionally associated with these industries (Kostënki knives and shouldered points) is scarce and highly questionable. The same applies to the “shovel-like” ivory object, typically related to the Pavlovian but with a doubtful determination as a shovel and no clear parallels in this and other industries of Gravettian tradition. The faunal remains revealed that hunting activities, which occurred between late summer and the beginning of winter, concentrated on reindeer. Nonetheless, new excavations and analyses are required to confirm all these preliminary results. In this sense, future work at the Abri I im Dorf can significantly contribute to our understanding of pre-LGM human settlement dynamics in the Upper Danube.

Evidence for an earlier Magdalenian presence in the Lone Valley of southwest Germany

After the Last Glacial Maximum (LGM) people associated with the Magdalenian resettled Central Europe, which had been uninhabited, or very sparsely inhabited, during the LGM. The precise timing and origin of this resettlement, however, remain unclear. We present new data from the Lone Valley of the Swabian Jura in southwestern Germany to improve our spatial and temporal understanding of this resettlement. Our work focuses on two Paleolithic sites: Vogelherd, a well-known cave originally excavated in 1931, and Langmahdhalde, a rock shelter approximately 2 km from Vogelherd that has been excavated since 2016. We report radiocarbon dates associated with the Magdalenian from both sites, lithic and organic artifact analysis from Vogelherd, and zooarchaeological, microfaunal, and preliminary lithic data from Langmahdhalde. These results reveal an earlier presence of people in the Lone Valley than previously thought, dating to before the Upper Magdalenian, while providing an improved paleoecological context of this resettlement. The available data suggest ephemeral use of the Lone Valley between ca. 19,500 and 16,500 cal yr BP, followed by regular occupation of the region. Our study highlights the advantages of bringing together data from multiple sites that are close together and were used during the same time in the past. In this case, the data from each site compliments each other and allows us to gain important insights into the Paleolithic settlement dynamics of southwestern Germany.

Bridging the spawner-recruit disconnect II: Revealing basin-scale correlations between zooplankton and lobster settlement dynamics in the Gulf of Maine

In recent decades, recruitment of young-of-year lobsters to benthic nursery habitats in the Gulf of Maine was regionally synchronized and exhibited correlative links with changes in the abundance of the copepod Calanus finmarchicus, a foundational zooplankton species of the pelagic food web. The spatial scale at which recruitment dynamics were correlated indicated that recruitment processes were not as strongly coupled to trends in spawner abundance as might be expected, but, rather, were influenced by common, ecosystem-scale processes. Here we explored how local- and basin-scale zooplankton dynamics and oceanographic indicators in the Gulf of Maine correlated with lobster settlement indices and each other since the late 1980s. Our analysis indicates that lobster settlement trends in southwestern Gulf of Maine study areas, from Midcoast Maine to Cape Cod Bay, tend to be significantly correlated with basin-wide C. finmarchicus dynamics and the composition of waters entering the Gulf of Maine through the Northeast Channel. In contrast, lobster settlement in the northeastern Gulf, from Penobscot Bay to the Bay of Fundy, tended to correlate more strongly to C. finmarchicus variability in the Bay of Fundy region, which was distinct in earlier years but converged with the broader basin-scale processes in the latter years. Our results are consistent with the hypothesis that the combined effect of climate-related declines in abundance and phenological shifts of C. finmarchicus have contributed to declines in lobster settlement over the past decade, and justify further research into the mechanisms of this interaction. These changes also align with the weakening influence of cold Labrador Slope Water and strengthening effects of warm Gulf Stream waters that precipitated an ecosystem-wide regime shift in the Gulf of Maine over the past decade and may have greater implications for lobster recruitment than previously suspected.

Holocene alluvial dynamics, soil erosion and settlement in the uplands of Macedonia (Greece): New geoarchaeological insights from Xerolakkos in Grevena

This paper addresses the interplay between Holocene landscape evolution and human settlement dynamics, drawing new evidence from the alluvial history of Xerolakkos, a continental stream in Grevena (Western Macedonia, Greece). We developed an integrated geoarchaeological survey combining remote sensing geomorphological mapping, litho-stratigraphic analysis and radiocarbon dating with the site evidence of a new archaeological survey. Results revealed four major alluviation phases, corresponding to 1) the beginning of the Holocene until the Early Neolithic (∼6300/6200 BCE), 2) the end of the Early and the Middle Neolithic (∼6000–5400 BCE), 3) from the Middle Bronze Age to the Late Roman period (∼1800 BCE – 500 CE), and 4) during the Byzantine and Ottoman eras (∼500–1800 CE), all separated by phases of floodplain incision. Furthermore, the effects of several Holocene Rapid Climatic Changes (RCC) are traced and discussed together with potential human responses; we also provide the first alluvial sequence recording the ∼6200 BCE (8.2 kyr BP) event in the Balkans. While the climate and the local geomorphological setting are considered the primary drivers behind instability and erosion during the Early and Middle Holocene, a landscape change starting in the Middle Bronze Age (after ∼1800 BCE) followed by a re-organisation of the rural economy in the Roman period suggests the increasing involvement of anthropogenic forcing which, by the Ottoman period, evolved into a dynamic situation between climatic variability and adaptive land management. Finally, we demonstrate how soil erosion in the upper catchment constitutes a serious taphonomic bias when studying the regional archaeological record.

Five Centuries of Settlement Dynamics and Mobility in the Northern Raja Ampat Islands of West Papua

ABSTRACT We explore changes to settlement and mobility in the northern Raja Ampat Islands (Waigeo, Gam, and Batanta) over the past five centuries, a time when speakers of several Austronesian languages were moving throughout the archipelago. The evidence shows: (1) some settlement relocations were rapid, occurring within a generation, while other settlements remained fixed for hundreds of years; and (2) there were numerous clan and family scale movements that led to high levels of intermarriage between language groups and settlements. The results demonstrate that far from being a place of stasis caught between the worlds of Maluku and New Guinea, Raja Ampat settlement and mobility were highly dynamic. This dynamism prompts us to rethink the relationship between today’s settlement locations, their language affiliations, and the meta-narratives about their recent population histories. We propose that the deeper past of Raja Ampat may have also been characterized by dynamic movement and social flux.

This study aims to assess the housing and settlement dynamics within the Kelurahan Ujung Menteng area. Findings reveal a range of challenges impeding housing and settlement progress, encompassing inadequate access to fundamental services like clean water, sanitation, and road infrastructure. Moreover, socio-economic factors significantly influence the community's quality of life. In light of these findings, the research advocates several strategic initiatives to enhance housing and settlement conditions in Kelurahan Ujung Menteng. These include enhancing the accessibility of essential infrastructure, implementing affordable housing schemes, and fostering community empowerment in decision-making processes concerning area development.

Through Time: Reconstructing Palaeolithic Occupations Through Use-Wear Analysis in the Middle Palaeolithic Site of Ciota Ciara (Borgosesia, Italy)

Lithic use-wear analysis, through defining site function and allowing reconstructing of patterns of human occupation, can contribute to our understanding of archaeological palimpsests. The Ciota Ciara cave represents an excellent case study for this methodology. Multidisciplinary research so far conducted on the materials recovered from the atrial sector of the cave distinguishes three archaeological units from a Middle Palaeolithic occupation of the site: stratigraphic units (SUs) 13, 14, and 15. Each unit is interpreted as referring to a period of numerous, superimposed episodes of human occupation, the characteristics of which we try to reconstruct and present in this work through use-wear studies. The functional analysis of lithic industries from the upper units (13 and 14) has already been published previously; here, we report corresponding new data from the lowest level, SU 15. By comparing the use-wear results from the three units and integrating the findings with data from the geoarchaeological, palaeontological, zooarchaeological, and technological studies, we attempt to reconstruct the different phases of human occupation represented in the site through time, contributing to current interpretations regarding settlement dynamics and human behaviour in the Middle Palaeolithic of north-western Italy.

Assessment of Informal Settlement in Central Kandahar: A Case Study of Area Within Four Historic Gateways

Afghanistan's post-war recovery, commencing in 2001 following the cessation of hostilities, precipitated rapid urbanization, notably witnessed by a substantial proliferation of informal settlements, primarily concentrated in Kandahar Province. This phenomenon, exacerbated by significant rural-to-urban migration and population expansion, has emphasized the imperative for exhaustive research aimed at comprehensively understanding its definitions, associated types and potential impacts of informal settlement. The proliferation of informal settlements in Kandahar's historic gateways presents a complex challenge necessitating meticulous and nuanced analysis. The research endeavors to undertake a comprehensive exploration of the definitional constructs of informal settlements, encompassing diverse typologies and their ramifications on urban settings. Central to this endeavor are key objectives aimed at scrutinizing squatter settlements, discerning their typologies, including Spontaneous Sheltering, Homeless Encampments, Nomadic Tents, Refugee Camps, Carts and Wagons, Squatter Settlements, Slums, Self-Help Housing, Shantytowns, Informal Subdivisions and Tenement Housing. Furthermore, the research aims to assess the effects associated with informal supplementary settlements, which encompass a broad spectrum of socioeconomic and environmental ramifications, such as Overcrowding, Poor Living Conditions, High Levels of Poverty, Limited Basic Services, Social Marginalization, Health Risks, Inadequate Sanitation Facilities and Vulnerability. Employing a mixed-methods approach integrating field observations, surveys, Case Studies and literature review, the research seeks to comprehensively understand the complexities of informal settlement dynamics, thus providing insights for informed policy formulation and interventions in urban planning.

Testing scale-dependent temporal and spatial biases in relative chronology using AMS 14C dating: A case study of Early–Middle Cucuteni-Tripolye sites in Southeastern Europe

Aiming at developing a syncretic chronology for Eneolithic sites in Romania, Moldova and Ukraine, this paper tests the hypothesis that relative material culture sequences will be preserved within lower-order taxonomic units and collapse within higher-order units. We examine relative sequences for sub-groups of the Cucuteni-Tripolye cultural complex (ca. 5050–2950 BCE) using Bayesian sequencing of extant and newly obtained radiocarbon dates. The traditional archaeological perspective holds that the space-time expansion of this cultural complex occurred in rapidly disseminated horizons, with little cross-regional variability in dating. Absolute dating efforts from the 1960s–2000s did little to clarify the situation, especially in the upper section of the Dniester river valley in Ukraine, where numerous older radiometric 14C dates present an improbably early chronology for sites of the Early and early Middle Tripolye periods (Tripolye A and BI). Here we present 21 new AMS 14C dates from early settlements in Southwestern Ukraine and Moldova, with results dating to the latter half of the fifth millennium and the beginning of the fourth millennium BCE. Eschewing the concept of monolithic horizons, we compile both old and new data into regionally distinct sequences, enabling a more nuanced examination of material synchronization and cross-regional settlement dynamics.

A story of hope and frustration: a wastewater-based agricultural frontier in the Algerian Sahara

ABSTRACT This study explores how wastewater reshapes the dynamics of agricultural settlement in the Algerian Sahara. It also discusses farmers’ hopes and frustrations around these dynamics. The study was carried out around the Berriane wastewater treatment facility. It is based on interviews with officials and farmers, a review of technical studies and direct field observations. We show how wastewater reuse regenerates traditional practices, such as the use of human waste as fertilizer and raw sewage to irrigate palm groves. We also discuss the problems that arise when the treatment plant is not managed properly, and the political ambivalence of State authorities regarding wastewater reuse.

Identification and quantification of projectile impact marks on bone: new experimental insights using osseous points

Shifts in projectile technology potentially document human evolutionary milestones, such as adaptations for different environments and settlement dynamics. A relatively direct proxy for projectile technology is projectile impact marks (PIM) on archaeological bones. Increasing awareness and publication of experimental data sets have recently led to more identifications of PIM in various contexts, but diagnosing PIM from other types of bone-surface modifications, quantifying them, and inferring point size and material from the bone lesions need more substantiation. Here, we focus on PIM created by osseous projectiles, asking whether these could be effectively identified and separated from lithic-tipped weapons. We further discuss the basic question raised by recent PIM research in zooarchaeology: why PIM evidence is so rare in archaeofaunal assemblages (compared to other human-induced marks), even when they are explicitly sought. We present the experimental results of shooting two ungulate carcasses with bone and antler points, replicating those used in the early Upper Paleolithic of western Eurasia. Half of our hits resulted in PIM, confirming that this modification may have been originally abundant. However, we found that the probability of a skeletal element to be modified with PIM negatively correlates with its preservation potential, and that much of the produced bone damage would not be identifiable in a typical Paleolithic faunal assemblage. This quantification problem still leaves room for an insightful qualitative study of PIM. We complement previous research in presenting several diagnostic marks that retain preservation potential and may be used to suggest osseous, rather than lithic, projectile technology.

What drives densification and sprawl in cities? A spatially explicit assessment for Vienna, between 1984 and 2018

The spatial arrangement of settlements constitutes a long-lasting legacy and shapes the prospects for transformations toward sustainability. Thus, understanding the drivers of changes in settlement patterns is essential. In this article, we present a spatially explicit, geostatistical analysis of settlement dynamics, and a qualitative investigation of its regulative, demographic, and economic drivers, using the example of Vienna, Austria between 1984 and 2018. Combining spatially explicit metrics of urban sprawl and cluster analysis, we analyzed high-resolution maps of buildings, population, and jobs to identify distinct settlement trajectories. Societal drivers of more or less sprawled settlement dynamics are analyzed with desk research and expert interviews. We distinguish five types of settlement dynamics: persistently dense areas with increasing use intensity, re-densification of dense areas, persistently sprawled areas, redensification of sprawled areas, and persistently isolated buildings. Urban renewal schemes have fostered the re-densification of dense areas in response to population growth and urban economic restructuring. The combination of urban renewal schemes and green space policies has successfully limited urban expansion. Challenges arise from the demand for single-family housing and corresponding zoning regulations. These factors solidify existing sprawled settlements, posing obstacles to the efficient re-densification of such areas crucial for sustainable urban development.
